This involves using a small clean plastic bag containing a small amount of lubricant. The O-ring is
inserted into the bag, worked around to evenly coat with lube while squeezing off excess, then taken
out of the bag and used in its location – Fig. 2.

(26) Another way is to apply a small amount of lubricant to the gloved index finger and massage the O-
ring between the thumb and index finger. Either way works, but the bag method tends to give better
distribution results and uses less lubricant.

Under most circumstances, a lubricant should be used very sparingly or not at all. In nearly all
scuba applications, if you can see the lubricant, too much has been applied. Before using any lubricant,
any existing lubrication should be removed before new is applied. In dynamic applications, it is used to
reduce excessive wear. Static O-rings do not generally require the use of lubricant.
(28) Where parts are not necessary to be lubricated, it is good practice to avoid getting any lubricant
on them, especially when the regulator is used with high oxygen content mixes. It also helps to keep
those parts clean and free of debris that will cling to the lubricant.
